Delta K40P
Powered Dual 10" Point Source Speaker


Product at a Glance
The British Acoustics K40P is a compact, high-performance point source speaker, designed as the vertically arrayable counterpart to the K40 LA. Combining versatility and exceptional power, the K40P is ideal for professional audio applications requiring precise sound coverage and high output. Equipped with a 90° x 30° waveguide, the K40P delivers focused and controlled sound dispersion, making it suitable for a wide range of venues and setups. Its innovative half-octagon array rigging method allows for seamless vertical arraying, ensuring optimal sound coverage and flexibility in deployment.
Powered by a 3000W Class-D amplifier, the K40P achieves incredible SPL levels while maintaining high efficiency and reliability. The same amplification system as the K40 LA ensures consistent performance, and the K40P is fully compatible with the Delta Audio Controller software, enabling advanced system configuration and real-time monitoring for large-scale setups. Despite its compact size, the K40P is engineered for unbelievably high SPL output, offering power and clarity that rival much larger systems. Built with robust construction and precision engineering, it delivers consistent, distortion-free performance even in demanding environments. The British Acoustics K40P sets a new standard for high-power point source speakers, combining compact portability, innovative rigging, and exceptional sound quality for modern audio professionals.
CRAFTSMANSHIP
Painstakingly Perfect Production

Over the years, craftsmanship has been closely linked with small scale individualistic production. Back in 1972, we started the same way. As we grew in scale & size, it was difficult to build each speaker individually, but quality control was of utmost importance as so switching to a general assembly line was simply not an option. So we wrote up a code, one quite like enigma, to ensure quality control. We selected the right partners, got the right tools, and in cases where those weren't available, we invented them. We grew slower than most as our aim was to last longer than most.
